I have a countdown timer inside updatepanel. When it reaches 00:00:00, it processes a huge amount of data and that point of time, i'd like to disable the submit button outside updatepanel. Simple btn.enabled = false is not working.

If that is even the right combination of controls to use.. I have a page that will display a list of files that have been processed or processing.. its not really time sensitive, but would like for the page to refresh the gridview every say every minutelonger(not determined yet)Is that the most optimal way to accomplish this, i mean if you are on the page, i dont want you to have to hit refresh to see any new records or status changes to the existing records..

This gives a quite strange result: Every 5s my whole page gives a full postback. When I comment in (activate) the asyncpostbacktrigger, the updatepanel does not give a full postback. In the PlayerItems_ItemDataBound I have the following code (which, I do think, do not matter):

[Code]....

When I create a NEW updatepanel, ItemsUpdatePanel1, it does not fire a full postback without the timer. I can even start copying items from ItemsUpdatePanel to ItemsUpdatePanel1, and suddenly the full postbacks happen. I tried 2 seperate times, and they started happening at different times. I simply want the UpdatePanel NOT to give a full postback, even without a timer.

GOAL: on a web page (vb.net) content in a placeholder will refresh with a different .ascx (user control) every 30 seconds (rotating 3 in total) and of course i dont want to refresh the whole page, just the placeholder.

I'm new at AJAX (that's my first problem - lol)

I set the timer up to call a function, but not sure how to go about refreshing the placeholder with a different ascx file. I'm sure i'll be using UpdatePanel to do this, but haven't been able to figure this out. Easy to replace a value in a label using AsyncPostBack trigger, but nothing on how to achieve this.

I don't understand what the problem is with this. It should be a simple operation yet it doesn't work.

I found samples on how to do this, when I apply the sample, it doesn't work.

In my page I have this:

[code]....

When I run the page, after 5 seconds it switches from the first image to the second image and never switches back to the first image.

When I debug with a break in the code-behind, it looks like the timer ticks twice for every tick. So, when the image is sample2, it then changes back to sample1 and then immediately ticks again and switches back to sample2 with no update-panel refresh in between.

I cannot use asyncFileUpload as it has too many restrictions which doesn't meet our requirement.

I'm able to add a updatepanel trigger to force the Button1 to perform a postback. after the file uploaded, I need to use a timer to do different tasks and return messages back to client with the timer. That is all fine.

However, when one upload is finished. I try to do it again. The FileUpload1.HasFile is "false". I don't know why. if I remove the timer, at the second time, the HasFile is "true". I think there must be something in the timer and disable the Button1's postback.

On the home page of my site I have an UpdatePanel with a Timer which ticks every couple of seconds. Un-related to that I have a user login forum (username / password) If you are typing your username into the textbox while the timer ticks, it takes focus off the textbox.

VS2010 ( Vb.net ).I have a masterpage that contains a gridview, giving stats and information on client files sent to us. This gridview is updated by means of a timer control every 10 seconds. In my grid I have an image field, to display either a tick .. if everything is ok or a cross for any problems.When the timer control timer event forces a gridview databind every 10 seconds.When the page first loads, i get the default red Cross in the gridview imagefield, however when the timer loops forces a 'databind' I lose the redCross and it is replaced with the default image control ( as if no url is set ) . Then I get a server 404 error.I am using the OnDataBound event to fire my vb sub. I have commented out evertything just to get a solid starting point but im still getting errors.

I'm searching for an example with an client timer that ticks synchronous with an server timer. Also there must be a button on the client side which can reset the server timer to an default value, and with this it also resets the client timer ofcourse. I tried it myself but it seems that there is some postback delay which makes it impossible for me to make it atleast look like it goes synchronous.

I hope somebody got an example for me, the button part is really important because by pressing that button the delay comes.

When my user sign in I want to show one Label control having Background color 'Green' for next 2 min's. After 2 min's it should become yellow and after 5 min's it should become red. I wrote sample prog for it. But I am not getting th proper output.

I am using timer control and update panel to change my page title based of how many new mails are coming just like the way gmail behaves. But the thing is it only works for the content or display the count right in my lblMailCount, but the page title never changes.

Asp.Net AJAX Timer control stops ticking when I right click on the page. Actually i am updating a label using timer control for every second. When I right click on the page the label is not getting updated. I mean the timer stops ticking.

i want to display time on my screen and therefore i used timer control inside update panel and set my timer interval to 1000 but the time displayed after 3 seconds i mean 56 -53-52-49..... how to solve this below is the code

I have a situation where I have a page in ASP.NET. In this page I have a RadioButtonList, which contains 5 solutions to a question. The RadioButtonList is feeded by an object, which has these solutions.I have a timer, which runs every second, to update loads of graphical controls. Everything works, BESIDES the RadioButtonList selection.This is what happends:

When I select an item in the RadioButtonList and the timer tick, the selectedIndex of the RadioButtonLIst value is 0. This means it selects the FIRST item in the list. However, IF I click an item, which has a "Yes" value in it (the value field can either have "No" or "Yes", it will stay at this item.First of all, I have NO idea why the timer re-select my RadioButtonList selection, as any other Page_Load event does nothing. And even if that makes sense, I have no idea why it just re-selects SOME of the answers..I have the following HTML code:
